Is a condensing or non-condensing tankless water heater better?

Not only is venting more cost effective with a condensing tankless water heater, but they’re also more efficient. All condensing tankless water heaters run above 90% efficiency, while non-condensing tankless water heaters usually run in the 80% range.

Why does my water heater have so much condensation?





Your water heater might also release condensate if you’ve just used a lot of hot water and the water refilling the tank is really cold. In some cases, condensation can indicate that the unit’s temperature setting is too low, in which case, you only need to increase your water heater’s temperature.

How much water should drain from a water heater?

How much condensate does a heat pump water heater produce?

approximately one to two quarts per day

Moisture or condensation can be a by-product of the GeoSpring Hybrid electric water heater depending on humidity and the run time of the heat pump. Condensate amount will vary according to these conditions (approximately one to two quarts per day).

How often should a condensate pump run?



It is essential that the condensate pump system is regularly checked for correct operation. The frequency will depend on the environment in which the unit is operating but should be a minimum of once every 3 months.

Which is better navien vs Rinnai?

Navien Water heaters have an advantage when it comes to being energy efficient. Navien units have UEF ratings of up to 0.96 while Rinnai Units max out at approximately 0.93. The more efficient the unit is, the less energy waste which translates to more energy savings.

What is the advantage of a condensing tankless water heater?

A condensing tankless water heater can recycle that extra heat. It only vents the vapor when it is no longer useful for the heating process, and is known as a closed system. The vapor from a condensing tankless water heater is much cooler. Therefore it doesn’t require the same expensive and elaborate venting material.

Can you vent a tankless water heater through the roof?

Tankless water heaters can vent through the roof or a side wall, creating more flexibility and options for placement. Traditional gas tank water heater require venting through the roof. Tankless water heaters use fans to blow exhaust from the unit horizontally, allowing vents to terminate on the side of a house.

Can I use PVC to vent my tankless water heater?



In most cases, PVC makes a great venting material. It’s the least expensive option and is easy to install. And it’s a good reason to consider a high-efficiency condensing unit.

What is the code for venting a tankless water heater?

ANSI Z223

The water heater must be vented in accordance with the section “Venting of Equipment” of the latest edition of the National Fuel Gas Code: ANSI Z223.

Can I use B vent for tankless water heater?

Type “B” gas vent can not be used on most of these heaters for this reason. Another reason this vent is required is that the vent systems are under pressure from the fan within the heater.
